    Abstract: A method and apparatus for controlling transmission of a channel quality indicator (CQI) in a wireless communication system are disclosed. A wireless transmit/receive unit (WTRU) determines, at each transmission time interval (TTI), whether a CQI timer has expired. The CQI timer is reset each time a CQI is sent out by the WTRU. If the CQI timer has expired, the WTRU determines whether a CQI reporting opportunity exists in a current TTI. The WTRU sends a CQI if a CQI reporting opportunity exists in the current TTI. Otherwise, the WTRU waits for a next TTI. The CQI reporting opportunity exists when there is uplink data to be transmitted in the current TTI, when the WTRU needs to send a positive acknowledgement (ACK) or a negative acknowledgement (NACK) in the current TTI, or when a dedicated physical control channel (DPCCH) burst is scheduled to be transmitted in the current TTI.

    Abstract: The present invention is related to a method and apparatus for facilitating lossless handover in a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a source evolved Node B (eNB), a target eNB, and a mobility management entity/user plane entity (MME/UPE) where the WTRU is in wireless communication with the source eNB. The source eNB determines to handover the WTRU to the target eNB, requests status reports from the WTRU, and requests handover to the target eNB. The handover request includes context information relating to the WTRU which is sent to the target eNB. The target eNB configures resources for the WTRU and transmits a handover response signal to the source eNB. The source eNB commands the WTRU to perform a handover to the target eNB and forwards data to the target eNB. The WTRU performs the handover to the target eNB.

    Abstract: A method and apparatus for signaling information indicating performance requirements that a WTRU commits to satisfying from the WTRU to permit a more efficient allocation of radio resources and increase network capacity. The WTRU may signal information to the base station that includes performance requirements that the WTRU commits to satisfying, that includes a code or a field associated with at least one performance requirement. In another embodiment, the signaled information indicates a change in performance requirements committed to by the WTRU. In yet another embodiment, the WTRU signals channel quality measurements, such as channel quality indicator (CQI) report messages, to the base station, which in turn infers certain information regarding receiver performance based on the channel quality measurements.

    Abstract: The present invention relates to hierarchical modulation (HM) and demodulation for global system for mobile communications (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN) evolution. In one embodiment, HM symbols are generated by generating primary modulated symbols based on a first bit group, generating secondary modulated symbols based on a second bit group, and combining the primary modulated symbols and the secondary modulated symbols. In another embodiment, the HM symbols are demodulated. In yet another embodiment, a received GERAN signal is converted to baseband complex symbol values, which are processed to produce training symbols and data symbols that carry pilot symbols. Channel parameters of the radio channel are estimated based on the training symbols. An equalized signal is generated based on the estimated channel parameters and data symbol. Primary and secondary demodulated symbols are generated based on the equalized signal.

    Abstract: A receiver sends hybrid automatic repeat request (H-ARQ) feedback for a current packet and at least one previous packet, whereby an error is detected based on the H-ARQ feedback. The receiver sends H-ARQ feedback with an identification of the packet or a sequence number of a packet that the receiver expects to receive next. The receiver stores a packet in a memory before combining the packet with a previously received packet, and decodes the stored packet after failing to decode a combined packet to avoid a corruption error. The receiver may set a timer when sending a NACK. If the receiver fails to receive a packet until expiration of the timer, the receiver initiates a process for recovering the packet. Each H-ARQ feedback may be associated with other attributes. Some H-ARQ processes may operate in an asynchronous mode while others in a synchronous mode in the same direction.

    Abstract translation: 接收机为当前分组和至少一个先前分组发送混合自动重传请求（H-ARQ）反馈，由此基于H-ARQ反馈检测到错误。 接收机发送H-ARQ反馈，其中包含分组的标识或者接收机期望接收的分组的序列号。 在将分组与先前接收到的分组组合之前，接收机将分组存储在存储器中，并且在未组合分组解码之后对存储的分组进行解码以避免损坏错误。 接收机可以在发送NACK时设置定时器。 如果接收方在定时器到期之前无法接收到数据包，则接收方发起恢复数据包的过程。 每个H-ARQ反馈可以与其他属性相关联。 一些H-ARQ进程可以以异步模式工作，而其他H-ARQ进程可以在同步方向上工作。

    Abstract: A mesh network includes a plurality of mesh points (MPs), a central database (DB) and a central controller (CC). The MPs are configured to broadcast quality of service (QoS) information over a wireless medium. Each MP may request QoS information directly from at least one other one of the MPs. The MPs store QoS information in the central DB and are configured to query the central DB QoS information associated with any of the MPs. Thus, QoS information is shared throughout the mesh network, and QoS policies are defined and updated where an MP may co-exist with another MP, an MP may co-exist with systems external to the mesh network, and an MP may co-exist with mesh access points (MAPs).

    Abstract: The present invention is related to an enhanced equalizer (106) using channel estimation. A scaled version of a channel estimate is used as an expected average behavior of the product of a transmitted signal and a received signal to implement Griffith algorithm. The present invention also uses advance or prediction of a channel estimate (112) to overcome the lag problem inherent in a least means square (LMS) algorithm in a time varying channel. Therefore, the present invention enables the use of a small step size while attaining the same tracking capability with a large step size. A channel estimate at some time in the future is used for updating equalizer filter tap coefficients. This may be performed with a prediction filter. Alternatively, a delay (104) may be introduced in the input data to the filter tap coefficient generator (114), which makes a channel estimate look like a prediction to the filter tap coefficient generator.

    Abstract translation: 本发明涉及使用信道估计的增强均衡器（106）。 信道估计的缩放版本被用作发射信号和接收信号的乘积的预期平均行为以实现Griffith算法。 本发明还使用信道估计（112）的提前或预测来克服时变信道中最小均方（LMS）算法中固有的滞后问题。 因此，本发明能够在以大的步长获得相同的跟踪能力的同时使用小的步长。 将来某个时间的信道估计用于更新均衡器滤波器抽头系数。 这可以用预测滤波器来执行。 或者，可以在输入数据中将延迟（104）引入到滤波器抽头系数产生器（114），这使得信道估计看起来像对滤波器抽头系数发生器的预测。

    Abstract: The present invention is related to a method of activating multiple bearer services in a long term evolution (LTE) wireless communication system including multiple bearers. At least one of the multiple bearers is activated during initial attach procedures which combine an attach procedure with activate packet data protocol (PDP) context activation procedures. In one embodiment, LTE attach procedures are implemented for multi-bearer services activation that establishes an LTE direct general packet radio service (GPRS) tunneling protocol (GTP) tunnel or normal GTP two-tunnels operation. In another embodiment, the initial attach procedures are used to activate a default PDP context to be followed by modified PDP context activation procedures for multi-bearer services activation. These procedures can be used to establish a modified LTE direct GTP tunnel or a normal GTP two-tunnels operation.
